Description

Technical Field

[0001] The utility model belongs to the technical field of liquid chromatographs, in particular to a base device of a liquid chromatograph. Background Art

[0002] Liquid chromatograph refers to an instrument that uses the difference in the distribution ratio of a mixture between liquid and solid or between two immiscible liquids to first separate the mixture and then analyze and identify it.

[0003] When a liquid chromatograph is in use, it is necessary to add a liquid chromatograph to detect the mixture according to the use requirements. Generally, multiple liquid chromatographs are stacked and placed, which saves space and facilitates the use of the instrument. However, when stacking, the liquid chromatographs may be unstable due to the lack of stacking, and may be accidentally touched, causing the liquid chromatograph to fall. For this reason, we propose a base device for a liquid chromatograph to solve the above-mentioned shortcomings. Utility Model Content

[0007] Preferably, the bottom of the connecting seat contacts the top of the corresponding base.

[0008] Preferably, both sides of the surface of the first clamping block are slidably connected to the inner surface of the second clamping block.

[0009] Preferably, the shortest compressed distance between the two second card blocks is greater than the front-to-rear width of the first card block after it rotates clockwise, and the distance between the front and rear two cross bars is greater than the front-to-rear width of the first card block after it rotates clockwise.

[0010] Preferably, lifting holes are provided at upper positions on both sides of the instrument one and the instrument two.

[0011] 1. The beneficial effect of the utility model is as follows: the utility model inserts the connecting seat connected to the bottom of the instrument two into the corresponding base, and slides the card block one on the inner surface of the card block two, thereby compressing the card block two, so that the card block two slides on the surface of the cross bar through the guide sleeve, thereby compressing the spring, and when the card block one slides to the top of the card block two, the limiting column on the top of the card block one is inserted into the limiting hole, thereby limiting the position of the limiting rod, and when the bottom of the card block one contacts the top of the card block two, the force generated by the spring itself resets the position of the card block two, thereby limiting the connection between the connecting seat and the base.

[0025] Embodiment 2:

[0026] Figure 1-4The base device of a liquid chromatograph of an embodiment of the utility model is shown, including a base 3 arranged between instrument 1 and instrument 2, and lifting holes 15 are provided at the upper positions on both sides of instrument 1 and instrument 2. By providing the lifting holes 15, it is convenient for users to lift and thus convenient for stacking the liquid chromatographs. The bottom of the base 3 is fixedly connected to the four corners of the top of instrument 1, and the bottom of the inner cavity of the base 3 is rotatably connected to a limit rod 4 through a bearing seat, and the top of the limit rod 4 is fixedly connected to a clamping block 5, and the top of the clamping block 5 is fixedly connected to a limit column 6.

The end face of the through-slot 7 is fixedly connected with a toggle handle, and the surface of the toggle rod 8 is slidably connected with the inner surface of the through-slot 7, so that the user can rotate the limit rod 4 clockwise to release the clamping connection between the block 1 5 and the block 2 12. The four corners of the bottom of the instrument 2 2 and the positions corresponding to the base 3 are fixedly connected with a connecting seat 9, and the front and rear positions on both sides of the inner cavity of the connecting seat 9 are fixedly connected with a cross bar 10, and the surface of the cross bar 10 is slidably connected with a guide sleeve 11, and the surface of the guide sleeve 11 is fixedly connected with the block 2 12, and the top of the block 2 12 contacts the bottom position of the block 1 5 after the clamping is completed.

A limiting hole 14 that is adapted to rotate and contact with the limiting column 6 is provided at the top of the inner cavity of the connecting seat 9.

When the bottom of the card block 15 contacts the top of the card block 2 12, the force generated by the spring 13 itself resets the position of the card block 2 12, thereby limiting the connection between the connecting seat 9 and the base 3. When separation is required, only the toggle handle needs to be turned clockwise so that the surface of the toggle rod 8 and the inner surface of the through groove 7 slide. The limiting rod 4 rotates counterclockwise, so that the card block 15 and the card block 2 12 are released from the connection.
